Cool idea RR. We just got the tile in our shower and now need to grout. We used an acrylic shower pan (3 x 5) cuz we were told it was best and foolproof. Maybe foolproof, but not necessarily the best. We just got final measurements and the quote for the shower enclosure glass. When the glass comes, an artist friend is going to sand blast an in-water steelhead scene. Gotta' have some fun with all this work.
